Ultra Low Sulphur Analyser in all Fuels, Biofuels and Oil, Compliant with ISO 20847 and ASTM D-4294

Horiba (France) is proud to release the SLFA 3000 series of ultra low sulphur analyser for biofuels, gasoline and petroleum products. It is compliant with current recommended methods: ASTM D4294 - 08a Standard Test Method for Sulphur in Petroleum and Petroleum Products by Energy Dispersive X-ray Fluorescence Spectrometry and ISO 20847:2004 specifies an energy dispersive X-ray fluorescence (EDXRF) test method for the determination of the sulfur content of motor gasoline, including those containing up to 2.7% (m/m) oxygen, and of diesel fuels.

With the new analyser, the typical detection limit is 2 ppm which is much below the lowest regulated content of sulfur (10 ppm). While a good detection limit is very useful, the crucial problem with energy dispersive X-Ray fluorescence is the matrix effect. Major developments for the new instrument are automatic matrix corrections with sophisticated algorithms and innovative spectrum analysis. Thanks to these new and unique features, the SLFA 3000 automatically makes matrix corrections for a wide range of sample C/H ratio (from 7 to 9) as well as for oxygen content up to 34 %.

So ultra low detection limits and matrix correction enable these analysers to be an essential tool for all type of products: From 0 - 10% S in sour crude to sweet crude to straight run gasoline to reformulated gasoline, etc… SLFA 3000 is your partner for pipeline, refinery or independent test laboratories with its short measurement times, extremely simple use and accurate, reliable results. It is the last member of the large Horiba Sulphur in Oil analyser family. It is the high end model of the EDX series including SLFA 2100/2800 for standards fuels, and the very famous SLFA-20 which the very compact and light model for “everywhere” analysis. For traces or very low sulphur levels, the SLFAUV21A, based on combustion and SO2 analysis using UV fluorescence method, is completing the range. It can also analyze the nitrogen. It is compliant with ASTM-D5453 and ISO 20 846.
